@debera – The uses of this product is enormous, now you no longer need to carry your travel charger or extra battery pack where ever you go. It's also great if this power could be stored on a power bank for later use.
Elizabeth, can't this principle use the other way around, where the flow will harvest the energy according to the movement of the peoples. If it is applicable it may be harvest more power to a specific work. Like lighting street lamps ..........etc.
Elizabeth this is really really interesting article, these are the innovations that we need in the future. I believe that if each person can produce their day today energy need there want be a much energy issue. This is the ideal way to start that cause that whether we like it or not we walk every day.
"DARPA's effort to harness 1–2 watts from continuous shoe impact while walking were abandoned due to the impracticality and the discomfort from the additional energy expended by a person wearing the shoes. Other energy harvesting ideas include harvesting the energy from human movements in train stations or other public places"
Looks like someone has tried this before.
I would guess that piezo output characteristics are less suitable to battery charging than the generator. Looks like piezo's are good for very high voltages, which is probably not what you want to charge a cell phone battery.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
